- the connector housing is of the waterproof type, and includes the waterproof wall which is formed in a bulged manner on the outer peripheral surface of the housing body, receiving the terminals therein, and extends in a direction away from the terminal-inserting side. Therefore, that side of the connector housing, facing away from the terminal-inserting side, can be surrounded by this waterproof wall. Therefore, when the connector housing is insert-molded in the resin material, the resin material (flash) is prevented from intruding into the connector housing through the waterproof wall side.
- the molded connector member includes the terminal-erecting holder fixing the terminal-assembled wire members and the wires. Therefore, the molded connector member can be formed, with the terminals and the wires held by the terminal-erecting holder, and therefore the displacement of the terminals and the wires during the molding operation is prevented. As a result, the quality of the molded connector member is enhanced.
- the terminal-erecting holder includes the frame body of a U-shaped cross-section, the plurality of terminal press-fitting holes formed through the top wall of the frame body, and the wire holding grooves formed in the free end of one of the two support walls of the frame body. Therefore, the displacement of the terminals and the wires during the insert-molding operation is prevented. Therefore, for example, the sandwiching engagement of the molding dies with the wires is prevented.
- the wires (each having the terminal press-fitted in the terminal press-fitting hole), held respectively in the wire holding grooves, are held in an L-shaped condition. Therefore, the efficiency of the molding operation, in which the wire module is molded with the terminals held in an upstanding condition, can be enhanced.
- the connector housing is insert-molded in the resin material which is different from the resin material of which the connector housing is molded. Therefore, for example, the connector housing is molded of the heat-resistant resin material whereas the resin material, in which the connector housing is insert-molded, is not heat-resistant, and by doing so, the material cost can be reduced. Therefore, the production cost of the wire module can be reduced.

connector housing 14 includes amale housing body 15, aperpendicular wall 16 formed on a central portion of anouter surface 15 a of thehousing body 15 over an entire periphery thereof, awaterproof wall 17 extending from an outer peripheral edge of theperpendicular wall 16, and aflash wall 21 formed on theouter surface 15 a of thehousing body 15 at a rear end thereof. A plurality ofterminal receiving chambers 18 are formed in thehousing body 15. Theperpendicular wall 16 is disposed perpendicularly to the outerperipheral wall 15 a. Thewaterproof wall 17 extends toward a fitting side (front surface) 15 b of thehousing body 15. - A
retaining step portion 19 is formed on the central portion of theouter surface 15 a over the entire periphery thereof, and aretaining recess 20 is formed in theouter surface 15 a at thefitting side 15 b, and theflash wall 21 is formed on and projects from theouter surface 15 a at a terminal-inserting side (rear surface 15 c). An annularwaterproof packing 22 is fitted on theouter surface 15 a, and is engaged with theretaining step portion 19. Twoannular lips 22 a are formed on an outer surface of thewaterproof packing 22. Apacking holder 23 for holding thewaterproof packing 22 is mounted on theouter surface 15 a. Aretaining projection 23 a is formed on an inner surface of thepacking holder 23, and is engaged in theretaining recess 20.Holes 23 b, corresponding respectively to theterminal receiving chambers 18, are formed in thepacking holder 23. Theflash wall 21 results from a flash (excess resin material squeezed out and solidified) formed when theconnector housing 13 is molded of a resin material. Theflash wall 21 holds the connector housing 14 against movement when insert-molding thewaterproof connector 13 with a resin material. -
Engagement holes 24 are formed in that portion of theouter surface 15 a of thehousing body 15 disposed adjacent to theflash wall 21.Engagement projections 25 a, formed on an outer surface of aterminal holder 25, are engaged in theengagement holes 24, respectively. Thus, theterminal holder 25 is attached to thehousing body 15. A plurality of wire passage holes 25 b, corresponding respectively to theterminal receiving chambers 18, are formed through theterminal holder 25, and thewires 6 are passed respectively through these wire passage holes 25 b. When theterminal holder 25 is attached to thehousing body 15, those portions of thewires 6, received within thewaterproof connector 13, are held or retained. - Referring back to FIG. 1, the
wire circuit member 12 comprises the plurality ofwires 6, extending outwardly from thewaterproof connector 13, and theinsulative covering layer 3 in which thewires 6 are insert-molded. - The
wires 6 are arranged at predetermined intervals. As shown in FIG. 5, a plurality ofprojections 3 b are formed on anupper surface 3 a of theinsulative covering layer 3. - The wire module of FIG. 1 is used in an engine room of a vehicle (not shown). Therefore, the
connector housing 14, shown in FIG. 3, need to be molded of a resin material having excellent heat resistance. Examples of such a resin material include polybutylene terephthalate (PBT) and low water absorption nylon (HPA). Theinsulative covering layer 3 is molded of a resin material different from the resin material of theconnector housing 14, and one example thereof is polypropylene (PPT) containing talc. - As shown in FIGS. 3 and 4, the resin material of the
connector housing 14 is different from the resin material of theinsulative covering layer 3, and a resin material, which is less expensive than the resin material of theconnector housing 14, is selected for theinsulative covering layer 3. By doing so, the cost of the wire module 1 can be reduced. - As shown in FIG. 6, a molding-die
main body 26, used in the production of the wire module 1 (that is, used for forming the insulative covering layer 3), comprises a vertically-movable (upwardly-downwardly movable) upper molding die 27, and a fixed-lower molding die 28 disposed beneath the upper molding die 27. The upper molding die 27 has ahousing cavity 27 a for receiving thewaterproof connector 13. The lower molding die 28 has awire receiving cavity 28 a for receiving thewires 6 extending outwardly from thewaterproof connector 13. Support pins 28 c for supporting theconnector housing 14 are formed upright on abottom surface 28 b of thewire receiving cavity 28 a. - Next, a method of producing the molded
connector member 10 employing thefemale terminals 4, as well as a method of producing thewire circuit member 12, will be described. - As shown in FIGS. 1 and 2, the
female terminals 4 are pressed to be clamped to thewires 6, respectively, thereby providing the plurality of terminal-assembledwire members 2. As shown in FIG. 3, the terminal-assembledwire members 2 are inserted into theconnector housing 14, thereby providing thewaterproof connector 13. As shown in FIG. 6, thewaterproof connector 13 and thewires 6, extending from thewaterproof connector 13, are set in the molding-diemain body 26. More specifically, thewires 6 are arranged at equal intervals in thewire receiving cavity 28 a in the lower molding die 28, and theflash wall 21 is supported on the support pins 28 c. In this condition, thewaterproof connector 13 is upstanding relative to the lower molding die 28, and the arrangedwires 6 are generally perpendicular to thewaterproof connector 13. Namely, thewaterproof connector 13 and thewires 6 are arranged to jointly assume an L-shape. - The upper molding die27 is moved downward, and the upper molding die 27 and the lower molding die 28 are mated together in a die-closed condition, with the
connector housing 14 received in thehousing cavity 27 a. In this condition, afree end 17 a of thewaterproof wall 17 is held in intimate contact with anupper surface 27 b of thehousing cavity 27 a, and an outerperipheral surface 17 b of thewaterproof wall 17 is held in intimate contact with an innerperipheral surface 27 c of thehousing cavity 27 a. When the molding-diemain body 26 is closed, a resin-fillingspace 29 is formed. - The resin material is poured through a pouring port (not shown), and is filled in the resin-filling
space 29. After the poured resin is cooled, the upper molding die 27 is moved upward, thus opening the molding-diemain body 26. As a result, the moldedconnector member 10 and thewire circuit member 12 are formed to provide an integral molded construction in such a manner that the resin material covers therear surface 15 c of thewaterproof connector 13 and the L-shapedwires 6. - Thus, the time and labor, required for removing the
flash wall 21 formed when molding theconnector housing 14 by the resin material, are saved (see FIG. 6), and therefore the process of producing theconnector housing 14 can be simplified. - The
terminal holder 25 is attached to thehousing body 15 of thewaterproof connector 13 from therear side 15 c thereof, and therefore when molding thewaterproof connector 13 with the resin material, the resin material (flashed resin) is prevented from intruding into thewaterproof connector 13 from therear side 15 c thereof. - In the first embodiment, although the
waterproof connector 13 is provided at one ends of thewires 6, thewaterproof connectors 13 can be provided at the opposite end portions of thewires 6, respectively, so as to provide the wire module 1. - In the case where the
terminals 5 are of the male type as shown in FIGS. 7 and 8, the moldedconnector member 11 comprises the terminal-assembledwire members 2, a terminal-erectingholder 30, which holds the terminal-assembledwire members 2, and theinsulative covering layer 3 in which the terminal-assembledwire members 2 and the terminal-erectingholder 30 are insert-molded. Ahood 31 for receiving a mating member (not shown) is formed integrally on a front side of the moldedconnector member 11 in a projected manner, and aprojection 32 for retaining the mating member is formed on anouter surface 31 a of thehood 31. - The
terminal 5 includes an electrically-conductive base plate 5 a, a tab-like portion 5 b formed at one end of thebase plate 5 a, astabilizer 5 c formed on thebase plate 5 a intermediate opposite end portions thereof, and a clamping portion 5 d formed at the other end of thebase plate 5 a. Thewire 6 is clamped to the clamping portion 5 d by pressing. - As shown in FIGS.9 to 11, the terminal-erecting
holder 30 includes aframe body 33 of a U-shaped cross-section, terminal press-fittingholes 34, and a holdingportion 35. - As shown in FIG. 9, the
frame body 33 includes atop wall 36, a pair ofsupport walls top wall 36 in the same direction, and a reinforcing plate 39 (see FIG. 10) covering one sides of thetop wall 36 andsupport walls holes 34 are formed through thetop wall 36. A plurality ofpartition walls 40 depend from an inner surface of thetop wall 36. The terminal press-fittingholes 34 are separated from one another by thepartition walls 40. The tab-like portion 5 b of theterminal 5 is press-fitted into the terminal press-fittinghole 34, so that theterminal 5 is held in an upstanding (erected) condition. Thetop wall 36 and the pair ofsupport walls 37 and 38 (shown in FIG. 9) are firmly fixed relative to each other by the reinforcing plate 39 (shown in FIG. 10). - As shown in FIG. 9, the comb-
like holding portion 35 is formed integrally on afree end 37 a of thesupport wall 37. The holdingportion 35 has a plurality ofwire holding grooves 41. As shown in FIGS. 9 and 12, a direction P of insertion of thewires 6 into the respectivewire holding grooves 41 is the same as a direction Q of press-fitting of theterminals 5 into the respective terminal press-fittingholes 34. Namely, eachwire 6 assumes an L-shaped posture within theframe body 33. Thewires 6 are fixedly held in thewire holding grooves 41, respectively, and therefore can be fixed against movement within the terminal-erectingholder 30. - As shown in FIGS. 10 and 11, a rearward
withdrawal prevention projection 42 is formed at a free end 38 a of theother support wall 38. The rearwardwithdrawal prevention projection 42 prevents the terminal-erectingholder 30 from being rearwardly withdrawn from the moldedinsulative covering layer 3. - A resin material for forming the insulative covering layer3 (FIG. 1) and the construction of the
wire circuit member 12 are almost the same as described above for the first embodiment, and therefore explanation thereof will be omitted. - As shown in FIG. 12, a molding-die
main body 43, used in the production of the wire module 1 (that is, used for forming the insulative covering layer 3), comprises a vertically-movable (upwardly-downwardly movable) upper molding die 44, and a fixed-lower molding die 45 disposed beneath the upper molding die 44. The upper molding die 44 hasterminal cavities 44 a for respectively receiving theterminals 5 held by the terminal-erectingholder 30. The lower molding die 45 has amolding cavity 45 a for receiving the terminal-erectingholder 30 and thewires 6 extending outwardly from the terminal-erectingholder 30. When the upper molding die 44 and the lower molding die 45 are mated together in a die-closed condition, a resin-fillingspace 46 is formed. The terminal-erectingholder 30 is held against abottom surface 45 b of themolding cavity 45 a in an upstanding condition, and thewires 6 are arranged over thebottom surface 45 b. - Next, a method of producing the molded
connector member 11 employing themale terminals 5, as well as a method of producing thewire circuit member 12, will be described. - As shown in FIG. 1, the
male terminals 5 are pressed to be clamped to thewires 6, respectively, thereby providing the plurality of terminal-assembledwire members 2. As shown in FIGS. 7 and 8, theterminals 5 of the terminal-assembledwire members 2 are press-fitted into the terminal press-fittingholes 34 in the terminal-erectingholder 30, and then thewires 6 of the terminal-assembledwire members 2 are forced respectively into thewire holding grooves 41 to be fixed thereto. As a result, thewires 6 are held in a generally L-shaped posture within the terminal-erectingholder 30. - As shown in FIG. 12, the terminal-erecting
holder 30 is placed on thebottom surface 45 b of themolding cavity 45 a in the lower molding die 45 in an upstanding condition, and thewires 6, extending from the terminal-erectingholder 30, are arranged at predetermined intervals. - The upper molding die44 is moved downward, and the upper molding die 44 and the lower molding die 45 are mated together in a die-closed condition, and the resin material is poured through a pouring port (not shown), and is filled in the resin-filling
space 46. After the poured resin is cooled, the upper molding die 44 is moved upward, thus opening the molding-diemain body 43. As a result, the moldedconnector member 11 and thewire circuit member 12 are formed to provide an integral molded construction in such a manner that the terminal-erectingholder 30 and thewires 6 are molded in this molded construction. - Thus, the
terminals 5 are first held in an upstanding (upright) condition by the terminal-erectingholder 30 while thewires 6 are fixedly held in thewire holding grooves 41, as shown in FIG. 12. Therefore, when the upper molding die 44 and the lower molding die 45 are mated together to close the molding-diemain body 43, the displacement of thewires 6, as well as the sandwiching engagement of the molding dies with thewires 6, can be prevented. And besides, thewires 6 can be easily formed into an L-shaped posture by the terminal-erectingholder 30. - Although the terminal-erecting
holder 30 is provided at one ends of thewires 6, the terminal-erectingholders 30 can be provided at the opposite end portions of thewires 6, respectively. - In the above embodiment, the
female terminals 4 can be clamped respectively to one ends of thewires 6 whereas themale terminals 5 can be clamped respectively to the other ends of thewires 6, as shown in FIG. 1. - As described above, in the present invention, the plurality of terminal-assembled wire members are arranged in the insulative covering layer. Therefore, the connector molded member can be formed, utilizing the terminals of the terminal-assembled wire members, and also the wire circuit member can be formed, utilizing the wires of the terminal-assembled wire members. Thus, the wire module, including the molded connector members and the wire circuit member, can be formed.
- In the case where the terminals are of the female type, the molded connector member comprises the connector housing, in which the terminal-assembled wire members are inserted, and the terminal holder attached to the terminal-inserting side of the connector housing. Therefore, when the terminal holder is attached to the connector housing, the terminal-inserting side of the connector housing is sealed. Therefore, when this connector housing in this sealed condition is insert-molded in the resin material, the resin material (flash) is prevented from intruding into the connector housing through the terminal-inserting side thereof during the molding operation.
- The connector housing is of the waterproof type, and includes the waterproof wall which is formed in a bulged manner on the outer peripheral surface of the housing body, receiving the terminals therein, and extends in a direction away from the terminal-inserting side. Therefore, that side of the connector housing, facing away from the terminal-inserting side, can be surrounded by this waterproof wall. Therefore, when the connector housing is insert-molded in the resin material, the resin material (flash) is prevented from intruding into the connector housing through the waterproof wall side.
- In the case where the terminals are of the male type, the molded connector member includes the terminal-erecting holder fixing the terminal-assembled wire members and the wires. Therefore, the molded connector member can be formed, with the terminals and the wires held by the terminal-erecting holder, and therefore the displacement of the terminals and the wires during the molding operation is prevented. As a result, the quality of the molded connector member is enhanced.
- The terminal-erecting holder includes the frame body of a U-shaped cross-section, the plurality of terminal press-fitting holes formed through the top wall of the frame body, and the wire holding grooves formed in the free end of one of the two support walls of the frame body. Therefore, the displacement of the terminals and the wires during the insert-molding operation is prevented. Therefore, for example, the sandwiching engagement of the molding dies with the wires is prevented.
- The wires (each having the terminal press-fitted in the terminal press-fitting hole), held respectively in the wire holding grooves, are held in an L-shaped condition. Therefore, the efficiency of the molding operation, in which the wire module is molded with the terminals held in an upstanding condition, can be enhanced.
- The connector housing is insert-molded in the resin material which is different from the resin material of which the connector housing is molded. Therefore, for example, the connector housing is molded of the heat-resistant resin material whereas the resin material, in which the connector housing is insert-molded, is not heat-resistant, and by doing so, the material cost can be reduced. Therefore, the production cost of the wire module can be reduced.
